| 摘 要： | 以我国西南喀斯特地区中心地带的贵州省为研究对象,通过建立灰色预测模型和时间序列预测模型,并将2007年和2008年的土地实际生产能力与土地预测生产能力进行精度检验,对贵州省2020年土地生产潜力进行综合预测。在此基础上,考虑温饱、小康及相对富裕3种生活类型所需的营养标准,对贵州省在退耕还林工程背景下的土地生产潜力进行评价。并针对评价结果,提出贵州省在退耕还林工程背景下实现土地可持续利用的相关建议。

| Abstract: | Guizhou province was selected as the research area,which is situated in the centre of karst areas in southwest China.Using GM (1,1) model and time series model,combing with the precision test between practical and forecast capacity of land productivity in 2007 and 2008,the potential land productivity in 2020 was forecasted.Considering different nutritional standards of three kinds including just having enough to eat and wear,relatively comfortable life and relatively richness,then the evaluation of potentia... |
